The Mid-Pleistocene Transition induced by delayed feedback and bistability [PDF]

, 2018
The Mid-Pleistocene Transition, the shift from 41 kyr to 100 kyr glacial-interglacial cycles that occurred roughly 1 Myr ago, is often considered as a change in internal climate dynamics.

BeeRootBot: A Bioinspired Robotic Probe Exhibiting Apical Growth through In Situ Soil Binding

Advanced Intelligent Systems, EarlyView.
This study introduces a novel method for consolidating subterranean exploration pathways in plant‐inspired robots by binding in‐situ soil with beeswax, a biobased material. This simultaneous advancement and wall‐lining process reduces penetration resistance, enhances exploration efficiency, enables communication and resource sharing, and promotes ...

Constraining Dynamical Dark Energy Models through the Abundance of High-Redshift Supermassive Black Holes

, 2011
We compute the number density of massive Black Holes (BHs) at the centre of galaxies at z=6 in different Dynamical Dark Energy (DDE) cosmologies, and compare it with existing observational lower limits, to derive constraints on the evolution of the Dark ...

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

$Om$ Diagnostic for Dilaton Dark Energy

, 2010
$Om$ diagnostic can differentiate between different models of dark energy without the accurate current value of matter density. We apply this geometric diagnostic to dilaton dark energy(DDE) model and differentiate DDE model from LCDM.

Fast generation of stability charts for time-delay systems using continuation of characteristic roots

, 2020
Many dynamic processes involve time delays, thus their dynamics are governed by delay differential equations (DDEs). Studying the stability of dynamic systems is critical, but analyzing the stability of time-delay systems is challenging because DDEs are ...

Pesticide Contamination in the Hair of Children From Colonia San Juan, a Rural Community in Paraguay

Drug Testing and Analysis, EarlyView.
Hair analysis in children from a rural community in Paraguay reveals exposure to organophosphates, pyrethroids, neonicotinoids, fungicides, herbicides, and endocrine disruptors, highlighting the urgent need for stricter environmental protections and preventive health measures. ABSTRACT Chronic exposure to pesticides can cause carcinogenic, reproductive,

Occurrence and Human Health Implications of Legacy Organochlorine Pesticides and Their Metabolites in Fruits and Vegetables of Bangladesh

Food Safety and Health, EarlyView.
Multiple OCP isomers and/or metabolites along with their parent compounds were detected in commonly consumed fruits and vegetables of Bangladesh, possibly attributed to both recently and historically applied OCPs. However, all the detected values were below 0.01 mg/kg, indicating no potential human health risks through dietary intake. ABSTRACT Globally,
